Further details

Cases who died before they could be interviewed about their mobile phone use were excluded in the publication of Hardell et al (2006) which might have led to bias. Therefore following studies were included in the present pooled-analysis including all alive and deceased cases between 1997-2003: The first case-control study regarding the period 1997-2000 was published in the publications 9520 and 9895, the second study regarding the period 2000-2003 in publications 12068 and 12259, and the third study regarding deceased cases and controls in the period 1997-2003 in publication 18358.
